“…Balancing all these requirements makes the development of biomaterial for bioprinting an extremely challenging process, forming one of the bottlenecks in the field of bioprinting for tissue engineering to date [3]. Combinations of hydrogel materials have been shown to exhibit a balance of these properties that allow for their use in a wide range of tissue engineering and bioprinting applications, with physiological relevance being increased with the number of different biomaterials combined; however, many biomaterials are expensive, which often becomes a limiting factor to the complexity of fabricated bioinks [4][5][6][7].…”

Synthesis of bioinks for bioprinting of respiratory tissue requires considerations related to immunogenicity, mechanical properties, printability, and cellular compatibility. Biomaterials can be tailored to provide the appropriate combination of these properties through the synergy of materials with individual pros and cons. Sodium alginate, a water-soluble polymer derived from seaweed, is a cheap yet printable biomaterial with good structural properties; however, it lacks physiological relevance and cell binding sites. Collagen, a common component in the extra cellular matrix of many tissues, is expensive and lacks printability; however, it is highly biocompatible and exhibits sites for cellular binding. This paper presents our study on the synthesis of bioinks from alginate and collagen for use in bioprinting respiratory tissue models. Bioinks were synthesized from 40 mg/mL (4%) alginate and 3 mg/mL (0.3%) collagen in varying ratios (1:0, 4:1, 3:1, 2:1, and 1:1); then examined in terms of rheological properties, printability, compressive, and tensile properties and cellular compatibility. The results illustrate that the ratio of alginate to collagen has a profound impact on bioink performance and that, among the examined ratios, the 3:1 ratio is the most appropriate for use in bioprinting respiratory tissue scaffolds.

“…Here, we propose to use this combination with cellulose nanofibers (CNF) (a promising green biomaterial) [63] as a versatile additive manufacturing process in which the direction of alignment of the anisotropic reinforcing agent can be rationally designed to obtain thin-film materials with a complex internal structure. CNF were selected as model building blocks for the present work because they form reasonably robust LbLfilms and because, in contrast to CNC, [34] CNF do not show any liquid crystalline behavior and thus cannot spontaneously selfassemble in helicoidal architectures.…”

Cellulose‐based nanocomposites are highly appealing for the development of next‐generation sustainable functional materials. Although many advances have been made in this direction, the true potential of fibrillar nanocomposites has yet to be realized because available fabrication approaches are inadequate for achieving precise structural control at the sub‐micrometer scale. Here a spray‐assisted alignment methodology of cellulose nanofibrils is combined with the layer‐by‐layer assembly into an additive manufacturing process in which the alignment direction of each cellulose layer is rationally selected to achieve thin films with a helicoidal arrangement of the nanofibrils. The helicoidal structure of the films is verified by measuring the circular dichroism (CD) of the samples. The sign and position of the structural CD peak show that the handedness and the pitch of the chiral structures can be easily tuned by deliberately selecting simple parameters, such as the number of consecutive cellulose layers sprayed in the same direction, and the angle of rotation between successive stacks of layers. To our knowledge, our approach is unique as it offers the possibility to prepare complex nanocomposite architectures with various nanoscale‐controlled sub‐structures from different anisometric objects, which is enabling novel designs of composite films with damage‐resistant and/or optical filtering functionalities.This article is protected by copyright.
